Best Code Signing Software 2026
Code signing choices involve how a release is signed, how keys are protected, and where approvals fit into your process. Compare cloud signing and HSM key protection with approval workflows and CI/CD signing. Certificate provision, supported targets, and trusted timestamping add useful dimensions when considering release requirements. Free-plan availability and paid-from pricing provide cost context. Cosign, SignPath, and SignPath Foundation are among the software options included. Review the listed capabilities against your release workflow and the targets your software needs to support, paying attention to how signing and approvals would fit together.
